A strange disease that attacks the human face, almost the entire face covered by fur, there are many people who call this disease as a disease of wolf fur.
When the hair begins to grow at face 2-year-old boy named Abys DeJesus, doctors immediately recognize the symptoms as Human Werewolf Syndrome.
The disease is called werewolf syndrome because people with this disease throughout his body will grow hair like werewolves (of course without the sharp teeth and claws).
Medical world know with this disease syndrome or Hypertrichosis Werewolf. Because of the rarity, the syndrome is caused by a chromosomal mutation that only affects less than 100 people in the world.
The researchers traced the location of the mutation changes experienced by people with this syndrome in Mexico on the X chromosome (one of two chromosomes in the human gene).
Professor Xue Zhang, an expert in genetics from the Peking Union Medical College, also has been testing a person with this disease and found that genetic abnormalities on chromosome X.
Genetic abnormality was found on chromosome X also belongs to sufferers who are in Mexico. Only, the gene abnormality found in people is different in China.
However, the extra DNA on their X chromosome that may have contributed to trigger the active genes in the surrounding hair grower.
Pragna Patel, scientists from the University of Southern California estimates that the culprit is a gene abnormality of this gene called SOX3, which is known to be responsible for hair growth.
“In fact, additional sequences are inserted (on the X chromosome), can trigger hair growth,” Patel said the research findings have been published in American Journal of Human Genetics.
However, Patel added, it can also be used for the study after receiving treatment against the disease baldness or hirsutism (excess hair growth).
